I guess I got a solution:
Tracking will now be given on the paypal receipt instead, which I have noticed it allows me to fill in the T/N.
Thank You for your discretion. I REALLY look forward to those 2300k LED’s. I’ve been looking for something like that for quite a while.
Even more modding, now the $10 headlamp I was talking about. This one has become my favorite multi-purpose headlamp, even though I have brighter ones (PL47G2 for example).
Original specs:
- 3W CREE XP-E R3 main LED w/clear reflector, around 5500K tint
- 2x 5mm white flood LEDs, around 6000K tint
- UI with 7 modes: Main bright, main dim, main blinking, flood on (main off), flood SOS, off. Hold for off in any mode.
- Tilting head, around 45 degrees downwards.
- 3xAAA batteries.
The headlamp (with 2300K modded flood LEDs)
Main LED beam & tint. Pretty tight beam and it has plenty throw. All the beam shots are a meter from the wall. Camera @5000K:

Original vs modded headlamp. Camera @5000K:
Pretty satisfied with this one, I’ve used the main light outdoors and it throws pretty far for a cheap headlamp. The flood LEDs are great for indoor use with the warm tint. I’m going to do a few of these and give them away to friends and family. People seem to be amazed by proper warm white LEDs because they’re so rare.
Bonus mod, 11-LED hurricane lantern with dimmer. Made out of metal and glass.
It’s using 2x D-batteries which makes for great battery life.
Original LEDs are supposedly warm white, modded LEDs are 2300K.
Original tint, quite cold for a light that’s advertised as “warm white”. Looks green-ish. Camera @4200K:

Added frosted glass for a more even light spread, looks much nicer.
It’s just for decoration purposes, but it works to light up a room in case of a power outage. Pulls 17mA at 3V on the lowest brightness, 320mA at 3V on full brightness. Sorry if these mods are tedious, I hope they bring some inspiration for the LEDs.
Keep them coming 
Is that lantern something that is currently available?
Actually, after seeing DBSAR’s collection, I’m thinking of getting an actual kerosene lantern of my own for use around my fire pit, but why not both?
And if anybody knows of an LED candle that isn’t difficult to mod, but will retain its flicker with an LED swap, I’m also interested.
My wife’s current candles all have amber LED’s. One type is easy to mod, but the flicker is built into the LED itself. The other type has actual wax molded around a plastic base and can’t be disassembled without destroying the wax.
Thanks. I received an email from Paypal this morning reporting the invoice has been updated with tracking info.
Yes Nismo I love seeing new ideas. And I just got my own bag to try my hand at a few.
i received some today! i like these a lot. 
I’ve got 2 of these:
28 LEDs
With a modified tail switch it can now both tail stand and fit an 18650 (unprotected though).
And one of these on the way:
21 LEDs
Should i get one of these too?
That 9 LED ones will most likely run unregulated with 3*AAA batteries. I’m not sure if I can recommend those.
They all run direct drive form 3x AAA in stock form.
So they need drivers, or at least some 7135 current regulators.
I used 12x 3400K rngwn leds to mod a Singfire 812A.

It is old stock, it seems they have not sold them for a couple of years, there was rust on the spring and even inside some of the 5mm leds was corrosion so their warehouse conditions are not optimal.
Nevertheless the build quality is a few grades up from what I can buy in the local stores for two euro’s:
*the ano seems really nice, not cheap at all
*the switch is press-fit but easy to disassemble (I swapped the black 16mm boot cap for a better quality orange one, soldered the loose spring to the switch-lip and made the press-fit a lot stiffer with a solder blob on the other switch-lip that presses against the housing).
*the head assembly is not press-fit but closes on the inside with an actual screwed-in retaining ring (I made two grooves with a saw in the ring to ease opening and closing, and there was no o-ring at the (plastic) lens so I added a nice orange one to match the boot cap, the rest of the light is o-ringed so now the light is submersible)
Then I swapped the 12 395nm leds for 3400K 95CRI leds and that was that.
With 3 AAA alkalines (one was not even full) I just measured 113 lumen so the leds are properly driven at ~30mA each. Tint out the front in the hotspot: CCT=3170K, duv=–0.0025, CRI=97.3, R9=85, R12=92, Rf=94.3, R9=102.6. The beam is a smooth flood.
Yes, there should be several available on eBay that are similar, but I got mine from Clas Ohlson (swedish hardware store) Link to the lantern.
The frosted glass is from another lantern bought at a local hardware store, one of those flickering flame ones. I didn’t like the color and animation of it so I’ve used it for parts.
I have modded the 9 LED 3aaa flashlight to add a 7135 regulator. The 7135 + & - pins will straddle the traces on the LED mounting board. remove the center pin and solder a wire from center tab to feed spring. …now isolate the spring where it normally contacts the outer trace on the board. I added insulator then glued it to the board. (My favorite shoe goo for that!)
Nice. :sunglasses:
I have one of those 12 LED ones too, and a silver one which is a bit different, but both have screw on heads.
The black one is about 10cm tall.
This means that is is possible to use an unprotected 21700 and a tail-stand-able tail switch, if you superglue the spring directly on the back of a small Omten and use a switch boot without a nub, and epoxy it all in the tail cap.
A single 7135 on the back of the LED board would be enough (29.2 mA per LED).
I’m gonna order one of those super crappy yellow plastic 9 LED ones too, just for fun. 
I modded a few 2-AA and 3-AA small Hurricane LED lanterns like that with generic WW LEDs, but these 2300K 5mm LEDs are high CRI and much closer to a real flame tint. I also found a bunch of small 2-AA ones at a local dollar store to mod too. (photos and mod topic eventually coming.)
I’ve searched local and online hardware stores in Norway for 5mm hurricane lanterns, I’ve only found the one I modded that has 2xD batteries. I don’t mind the D batteries since they last a good while, but it would be nice to use some Ni-Mh AA since I’ve got loads of them.
I’ll keep on searching though, would be nice with something smaller and more compact. I’m also scavenging eBay and AliExpress.
The big issue with using the NiMH AA cells as 2S, is their nominal voltage is two low, ad below the forward voltage of the LEDs. (for NiMH you need to use 3-series with a 47 ohm 1/4 watt resistor to get the correct output. 2AA Alkaline cells have a higher voltage and can run a LED without a driver, (i use a simple 7.5 ohm resistor in series with the LED for running 2 alkaline or ZincCarbon cells.
Is anyone in the US who has received theirs able to post how long they took to arrive?
Mine have been listed as sitting at “SUVARNABHUMI MAIL CENTRE” for almost 3 weeks now.
